Step 2: Configure the Java Development Kit (JDK)

1. Locate Your JDK Installation1:
   • If you already have the JDK installed, note its installation path (e.g., C:\Program Files\Java\jdk-xx.x.x). If not, Go to the Oracle JDK download page: Oracle JDK Download.
2. Set up JDK in IntelliJ IDEA1:
   • Open IntelliJ IDEA.
   • Go to File > Project Structure > SDKs.
   • Click the + icon and select “Add JDK”.
   • Browse to your JDK installation directory and select it.
   • Click “OK”.
   • Apply the changes.

(if JDK is not automatically detected)

Sometimes, IntelliJ IDEA may not automatically detect the JDK. In that case, you need to set up environment variables manually.

1. Open System Properties
   • Search for “Environment Variables” in the Start menu and select “Edit the system environment variables”.
2. Click “Environment Variables…” at the bottom of the System Properties window.
3. Set JAVA_HOME
   • Under “System variables”, click “New…”.
   • Variable name: JAVA_HOME
   • Variable value: The path to your JDK installation directory (e.g., C:\Program Files\Java\jdk-xx.x.x)
   • Click “OK”.
4. Edit the Path Variable
   • Find the “Path” variable in the System variables list, select it, and click “Edit…”.
   • Click “New” and add %JAVA_HOME%\bin to the list.
   • Click “OK” to close all windows.
5. Verify the Configuration
   • Open Command Prompt (search for “cmd” in the Start menu).
   • Type java -version and press Enter. You should see the installed Java version information. If it shows an error, double-check your environment variables.
